General hints for bug reports:
|
|
|
|
|
|
|
|
|
|
- keep the items small
|
|
|
|
|
|
|
|
|
|
- do not provide excessive information on how to reproduce the bug
|
|
|
|
|
if this is obvious
|
|
|
|
|
|
|
|
|
|
- if a bug is partly fixed, report it as "fixed" and a new bug item
|
|
|
|
|
that contains the unfixed part only
|
|
|
|
|
|
|
|
|
|
- check this list regularly, comment on the marked items.
|
|
|
|
|
|
|
|
|
|
- plain ASCII text please, not much more than 70 chars per column

2001-08-03 17:10:22 +00:00
|

|
- I know the latex code of a lot of math symbols displayed by lyx,
|
|
|
|
|
but not all of them. Thus I have to use the math panel for only a single
|
|
|
|
|
symbol in a formula. I think it would be very useful, if the latex code
|
|
|
|
|
of the symbol would be displayed as a hint, if the mouse positioned over
|
|
|
|
|
it.

- the most annoying bug by far: bold is "inherited" to super and subscripts.
|
|
|
|
|
|
2001-09-13 16:41:05 +00:00
|
|
|
|
// - when you get into equation array mode, the previous equation(s)
|
|
|
|
|
// remain(s) unaligned. I would be soo much faster to have LyX pick the
|
|
|
|
|
// last equal sign from the previous line as a reference for the alignment
|
|
|
|
|
// (and a good heuristic for the 80% of cases, with the advantage that we
|
|
|
|
|
// don't lose anything enforcing it). This is another case that slows down
|
|
|
|
|
// a lot when typing because, as the previous one, requires going back
|
|
|
|
|
// and correcting.
|
2001-08-03 07:33:59 +00:00
|

|
|
2001-10-23 07:33:03 +00:00
|
|
|
|
// - the movement is sometimes clumsy inside this arrayed equations: ie.
|
|
|
|
|
// C-a (or "home" are understood as "beginning of the formula" instead of
|
|
|
|
|
// "beginning of the equation". Again, a lot of movement has to be made.
|
|
|
|
|
// I suggest mapping "beginning of doc" with "beginning of formula" and so
|
|
|
|
|
// on (very intuitive), in case you don't deem appropriate the "namespace
|
|
|
|
|
// idea" below.
|
2001-08-03 07:33:59 +00:00
|
|
|
|
|
|
|
|
|
//- movement between macro boxes is also weird, but in this one it's perhaps
|
|
|
|
|
// just me.
|
|
|
|
|
|
|
|
|
|
- I suggest creating a different "kewybinding namespace" for the formulas,
|
|
|
|
|
since you could put to good use all those keybindings from the menu (M-?,
|
|
|
|
|
C-?) thath currently do their job PLUS getting you out of the formula.
|
|
|
|
|
Seriously, it'd be great to have more keys free, so M-d t would be time
|
|
|
|
|
derivative and M-d ? derivative with respect to the variable ?. And so on.
|
|
|
|
|
|
|
|
|
|
- I'm no experienced C++ programmer, but if you consider it appropriate, I
|
|
|
|
|
could write a scritp in python for this one (I'm also very optimistic). Tell
|
|
|
|
|
me what you think:
|
|
|
|
|
|
|
|
|
|
Flattening macros. Sometimes it's annoying the fact that once you have
|
|
|
|
|
written a macro, you can't touch at it's "constant parts". I call flattening
|
|
|
|
|
to the process of substituting all macros with LaTeX code.
|
|
|
|
|
|
|
|
|
|
Task: designing a macro substitution system that reads from a file
|
|
|
|
|
(possibly the same file as the document's) the macros and parses the document
|
|
|
|
|
doing the appropriate replacements
|
|
|
|
|
|
|
|
|
|
This is very useful, because sometimes you have a big expression in a macro
|
|
|
|
|
and you want to change an index only. What do you do then?. You retype
|
|
|
|
|
everything (perhaps several times in the document) or you create extremely
|
|
|
|
|
generic and parametrizable macros that aren't very fast to fill in the
|
|
|
|
|
majority of cases.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- undo-redo seems too coarse in math-mode. You end up losing substantial
|
|
|
|
|
fragments of your formula. I hate that when it affects tensors,;).
|
|
|
|
|
|
|
|
|
|
- cut&paste inside math-mode doesn't work the X fashion (middle button doesn't
|
|
|
|
|
paste anything).
|
|
|
|
|
|
|
|
|
|
- I remember having heard that a search-replace function was planned, so I
|
|
|
|
|
won't repeat that. Only that the flattening option would be then easier to
|
|
|
|
|
implement on top of that.
|

2001-09-14 11:03:41 +00:00

|
// - There's something I keep wondering about.. how do new math symbols get
|
|
|
|
|
// into LyX. Do they get ever?. I don't know if it can be done, but if you
|
|
|
|
|
// tell me where to "draw" those symbols or how, I would very glad start
|
|
|
|
|
// doing it. LyX deserves to have support (visual support) for all the
|
|
|
|
|
// AMSTeX constructs. But there must be something structural going on
|
|
|
|
|
// there, because otherwise more math symbols would be ready by now..
|
|
|
|
|
// just a thought.
|
2001-08-03 07:33:59 +00:00
|
|
|
|
|
|
|
|
|
- Some math symbols aren't very well supported (to my knowledge). I'm
|
|
|
|
|
thinking of underbraces with extra data in them,or [] options.

Herbert Voss:
|
|
|
|
|
|
|
|
|
|
- it's not possible to enter superscript when the
|
|
|
|
|
^-char works as a dead key. with the second ^-
|
|
|
|
|
or the space the cursor jumps outside the mathbox.

|
|
|
|
|
|
|
|
- I've been using Lyx for a year or two now, and I have some thoughts on
|
|
|
|
|
improving the interface. Not the GUI, as such, but the basic Human-Machine
|
|
|
|
|
interface --- the efficiency with which I can enter information into it.
|
|
|
|
|
|
|
|
|
|
There are a couple of general principles I'm try to uphold here:
|
|
|
|
|
|
|
|
|
|
a) If something's easy & quick in LaTeX then it should be easy & quick in
|
|
|
|
|
LyX (unless it really isn't very common). b) Actions which are used
|
|
|
|
|
frequently should be a single key-press, even if that's not very easy to
|
|
|
|
|
remember. You learn it. c) Actions which are used rarely should be
|
|
|
|
|
mnemonic -- easy to remember -- even if they are multiple keypresses.
|
|
|
|
|
Things you do rarely you care less about the time it takes to perform.

// 2) Math-mode entry Under the xemacs keybindings, which I use, (damn it,
|
|
|
|
|
// I don't want to confuse my poor muscle memory more than necessary by
|
|
|
|
|
// learning too many different bindings for the same actions), the key
|
|
|
|
|
// sequence to enter math-mode is 'M-c m'. I'm not sure exactly what to
|
|
|
|
|
// propose instead, but I really think this needs to be only one keypress.

As an aside, you may think that I'm whining over nothing. However, when
|
|
|
|
|
you enter math mode as often as I do (often more than once a sentence) it
|
|
|
|
|
gets very annoying, especially as compared to simply typing '$' in plain
|
|
|
|
|
emacs. Also, you may say 'why don't you just change your bindings file?'. I
|
|
|
|
|
will ;) but I wanted to start some discussion on this since it can benefit
|
|
|
|
|
everyone!
|
|
|
|
|
|
|
|
|
|
More serious, though, than the number of characters which need to be typed
|
|
|
|
|
is the confusing nature of the command. 'M-c m', typed once, puts you into
|
|
|
|
|
math-mode. However, typing 'M-c m' again doesn't put you out of math-mode
|
|
|
|
|
--- it puts you into math-text mode. Then hitting it again puts you back
|
|
|
|
|
into normal math-mode. IMO, 'modal' keys should either be idempotent (so
|
|
|
|
|
hitting it the second time does nothing) or self-inverting. In fact, the
|
|
|
|
|
inverse to 'M-c m' is either 'ESC' or simply a space typed at the end of
|
|
|
|
|
the block --- which is confusing, since they're not of the same 'shape' as
|
|
|
|
|
the command that got you in there.
|
|
|
|
|
|
|
|
|
|
Now, I'm not saying that 'space' shouldn't be allowed as a short-cut to get
|
|
|
|
|
you out of math-mode; it's a most useful and natural one, I like it a lot.
|
|
|
|
|
However, on balance I think M-c m should also have that effect.
|
|
|
|
|
|
|
|
|
|
3) Math-mode inconsistencies
|
|
|
|
|
|
|
|
|
|
Sometimes 'the same action' has the same keystroke both within and
|
|
|
|
|
without math-mode. This is very sensible. However, it is very annoying when
|
|
|
|
|
they don't behave the way you're expecting them to.
|
|
|
|
|
|
|
|
|
|
For example, 'M-c e' puts you into 'emphasise' mode. Ignoring the fact
|
|
|
|
|
that in text mode this is italics, and in math-mode it stands for the
|
|
|
|
|
calligraphic character set, I think of these as the same action, so I like
|
|
|
|
|
the fact that they have the same keys. However, in math-mode, 'M-c e' is
|
|
|
|
|
idempotent, (and you need 'M-c space' to get back into normal) whereas in
|
|
|
|
|
text-mode 'M-c e' is self-inverse. These are the two possibilities I listed
|
|
|
|
|
as acceptable before, but consistency would be nice ;-) IMO, self-inverse
|
|
|
|
|
would be best for both.
|
|
|
|
|
|
|
|
|
|
4) ERT in math-mode
|
|
|
|
|
|
|
|
|
|
Math-mode doesn't handle ERT very well at all. It flips back out of
|
|
|
|
|
TeX-mode as soon as you type any special character. Very annoying if I
|
|
|
|
|
wish to typeset an \xymatrix inside math-mode (see also my comment above
|
|
|
|
|
about table-like environments), since I can't type the &. In fact, my
|
|
|
|
|
xymatrices end up as $$\xymatrix{..}$$ in text-mode ERT. Also rather
|
|
|
|
|
annoying when you want to use a \macro with more than one argument (but not
|
|
|
|
|
fatally so).
|
|
|
|
|
|
|
|
|
|
5) Proposal : a 'ligatures' or 'autocorrect' system
|
|
|
|
|
|
|
|
|
|
One of the very minor, but useful, features of TeX is the way it lets you
|
|
|
|
|
type the nearest approximation to what you want using a 'typewriter
|
|
|
|
|
keyboard', and substitutes the typographically neat equivalent. In
|
|
|
|
|
particular, 'fancy' quotes (") and en and em dashes (---). I propose that
|
|
|
|
|
this UI element could be taken up a level into LyX, with a system that does
|
|
|
|
|
the following (for example):
|
|
|
|
|
|
|
|
|
|
-> becomes \rightarrow
|
|
|
|
|
<- becomes \leftarrow
|
|
|
|
|
=> becomes \Rightarrow (etc..)
|
|
|
|
|
==> becomes \Longrightarrow (etc..)
|
|
|
|
|
|
|
|
|
|
This may only be appropriate in math mode, of course. This family bug me
|
|
|
|
|
in particular because they take ages to type using a \-escape. Undoubtedly
|
|
|
|
|
sharp minds will think of others, and also we need some way of actually
|
|
|
|
|
typing those sequences as literals when we want them.
|
|
|
|
|
|
|
|
|
|
6) Scope macros:
|
|
|
|
|
|
|
|
|
|
The current macro system is clever, but could be neater. One improvement
|
|
|
|
|
I'd like is to let LyX know about TeX's scoping rules...

Yves Bastide:
|
|
|
|
|
|
|
|
|
|
- use AMS's \text instead of \mbox. It supports accented characters,
|
|
|
|
|
among others... (selected via validate()?)

// - An inline equation does not get a number, so putting a label there is not
|
|
|
|
|
// overly sensible...
|
|
|
|
|
// Ok. In that case show a message in the bottom similarly as the message
|
|
|
|
|
// "you cannot type two spaces this way". Eg. "You can insert math labels
|
|
|
|
|
// only in display mode"

:: Not a bug. It's allowed by LaTeX and there might be other reasons for
|
|
|
|
|
:: putting labels there. I won't add extra code to disable this.
